Set up a model that has a easy to manage user interface
allow people to adjust the parameters or add new elements
similar to the simulations for GPI that Maryland uses
Other examples:
Northwest Power Planning Council, discovered downstream smolt loss from predation
explore the impact of choices
explore the relative strength of the different parameters
need an open modeling environment that makes the assumptions clear
supports democratic processes
